Improve Prometheus Metrics #3716

Open kevarr opened 1 month ago

kevarr commented 1 month ago

Is your feature request related to a problem?

I couldn't find any documentation for what metrics the "metrics-server" port exposes.

Additionally, I couldn't configure the Helm Chart to not scrape these metrics, as my scrape_configs are looking at the prometheus.io/* annotations and these cannot be removed without enabling a ServiceMonitor.

Describe the solution you'd like

Thanks @huangm777, ended up finding some metrics I could use, namely the aws_api ones. Still I think I would benefit from having some of these documented. When I find time I'll try to open a PR for this
